Several new PtII and PdII complexes bearing the enantiomerically pure (1R,2R)-(–)-l,2-cyclohexanediamine (dach) ligand, of general formula [MX2{(1R,2R)-dach}], where M = Pt or Pd, X2 = cis- or trans- or (1R,2R)-1,2-cyclohexyldicarboxylate anions, have been synthesized and characterized physicochemically and spectroscopically. These complexes have been screened in vitro against the three tumour cell lines K562, HeLa and L929, and the results obtained were compared with those of the reference standards, cisplatin, carboplatin and oxaliplatin; the known antitumour drugs. The single crystal X-ray structure determination of the [Pt(C2O4)(cis-dach)] complex has been discussed and compared with that of oxaliplatin, [Pt(C2O4){(1R,2R)-dach}]. 相似文献

[(PhSnS3)2(CuPPhMe2)6], a Hexanuclear Copper(I) Complex with PhSnS3 Ligands Na3[PhSnS3] which is available by the cleavage of Ph4Sn4S6 with Na2S in aqueous THF reacts with the copper(I) complex [(PhPMe2)bipyCuCl] to give the hexanuclear copper(I) compound [(PhSnS3)2(CuPPhMe2)6] ( 1 ). 1 crystallizes in the space group P21/n with a = 1343.4(3) pm, b = 1134.5(2) pm, c = 2353.0(7) pm, β = 98.04(3)° (at 220 K). The molecular structure of 1 consists of six Cu(PPhMe2) groups which are bridged by two PhSnS3 units. The copper atoms are coordinated by two sulfur atoms and a terminal phosphine ligand in nearly planar arrangement with Cu‐S distances ranging between 223.6(2) and 232.9(2) pm. 相似文献

Activation of Carbon Disulfide on Triruthenium Clusters: Synthesis and X‐Ray Crystal Structure Analysis of [Ru3(CO)4(μ‐PCy2)2(μ‐Ph2PCH2PPh2)(μ3‐S){μ3‐η2‐CSC(S)S}] [Ru3(CO)4(μ‐H)3(μ‐PCy2)3(μ‐dppm)] ( 2 ) (dppm = Ph2PCH2PPh2) reacts with CS2 at room temperature and yields the open 50 valence electron cluster [Ru3(CO)4(μ‐PCy2)2(μ‐dppm)(μ3‐S){μ3‐η2‐CSC(S)S}] ( 3 ) containing the unusual μ3‐η2‐C2S3 mercaptocarbyne ligand. Compound 3 was characterized by single crystal X‐ray structure analysis. 相似文献

The tris(2,4‐dimethylpentadienyl) complexes [Ln(η5‐Me2C5H5)3] (Ln = Nd, La, Y) are obtained analytically pure by reaction of the tribromides LnBr3·nTHF with the potassium compound K(Me2C5H5)(thf)n in THF in good yields. The structural characterization is carried out by X‐ray crystal structure analysis and NMR‐spectroscopically. The tris complexes can be transformed into the dimeric bis(2,4‐dimethylpentadienyl) complexes [Ln2(η5‐Me2C5H5)4X2] (Ln, X: Nd, Cl, Br, I; La, Br, I; Y, Br) by reaction with the trihalides THF solvates in the molar ratio 2:1 in toluene. Structure and bonding conditions are determined for selected compounds by X‐ray crystal structure analysis and NMR‐spectroscopically in general. The dimer‐monomer equilibrium existing in solution was investigated NMR‐spectroscopically in dependence of the donor strength of the solvent and could be established also by preparation of the corresponding monomer neutral ligand complexes [Ln(η5‐Me2C5H5)2X(L)] (Ln, X, L: Nd, Br, py; La, Cl, thf; Br, py; Y, Br, thf). Finally the possibilities for preparation of mono(2,4‐dimethylpentadienyl)lanthanoid(III)‐dibromid complexes are shown and the hexameric structure of the lanthanum complex [La6(η5‐Me2C5H5)6Br12(thf)4] is proved by X‐ray crystal structure analysis. 相似文献

The Crystal Structures of (NBu4)[(Ph3Sn)3(MoO4)2] and (NBu4)[(Ph3Sn)3(MoO4)2]·CH3CN: Organotin Molybdates with Novel 3D Networks The reaction of (NBu4)2[Mo6O19] with Ph3SnCl and NBu4OH in acetonitrile as solvent leads to the formation of (NBu4)[(Ph3Sn)3(MoO4)2] ( 5 ). 5 and (NBu4)[(Ph3Sn)3(MoO4)2]· CH3CN 6 have been characterized by single crystal structure analysis at 220 K. 5 crystallizes monoclinic with a = 1429.5(4) pm, b = 2292.2(3) pm, c = 2269.7(5) pm, β = 107.42(3)°, space group Cc, 6 crystallizes orthorhombic with a = 1820.5(1) pm, b = 1848.6(2) pm and c = 2143.9(1) pm, space group P212121. The crystal structures of 5 and 6 consist of isolated (NBu4)+ cations and anionic 3D networks of Ph3SnO2 trigonal bipyramides and MoO4 tetrahedra which are linked by common oxygen atoms. 相似文献

Coordinatively Unsaturated Diruthenium Complexes: Synthesis and X‐ray Crystal Structures of [Ru2(CO)3L(μ‐η1 : η2‐C≡CPh)(μ‐PtBu2)(μ‐Ph2PCH2PPh2)] (L = CO, PnBu3) [Ru2(CO)4(μ‐H)(μ‐PtBu2)(μ‐dppm)] ( 1 ) reacts with several phosphines (L) in refluxing toluene under substitution of one carbonyl ligand and yields the compounds [Ru2(CO)3L(μ‐H)(μ‐PtBu2)(μ‐dppm)] (L = PnBu3, 2 a ; L = PCy2H, 2 b ; L = dppm‐P, 2 c ; dppm = Ph2PCH2PPh2). The reactivity of 1 as well as the activated complexes 2 a – c towards phenylethyne was studied. Thus 1 , 2 a and 2 b , respectively, react with PhC≡CH in refluxing toluene with elimination of dihydrogen to the acetylide‐bridged complexes [Ru2(CO)4(μ‐η1 : η2‐C≡CPh)(μ‐PtBu2)(μ‐dppm)] ( 3 ) and [Ru2(CO)3L(μ‐η1 : η2‐C≡CPh)(μ‐PtBu2)(μ‐dppm)] ( 4 a and 4 b ). The molecular structures of 3 and 4 a were determined by crystal structure analyses. 相似文献

The 3-(N,N-Dimethylamino)prop-1-enyl Group as a Chelate Ligand in Indium Organyls InBr3 reacts with Me2NCH2CH?CHMgCl (molar ratio 1 : 2) to form (Me2NCH2CH?CH)2InBr ( 1 ) as the first indium alkenyl compound with amino-functionalized alkenyl groups. The X-ray structure determination shows the formation of a chelate complex. 1 crystallizes in the orthorhombic space group Fddd with the unit cell parameters a = 14.904(2) Å, b = 17.140(1) Å and c = 21.035(2) Å. By reaction of Me2InBr with Me2NCH2CH?CHMgCl (molar ratio 1 : 1) (Me2NCH2CH?CH)InMe2 ( 2 ) is formed as a colorless, at room temperature liquid, monomeric compound. The n.m.r. and mass spectra are discussed. 相似文献
